Chandan Kumar,Bhoopendra Kumar Kushwaha,Amit Kumar,Deepak Kumar Jarwal,Rishibrind Kumar Upadhyay,Abhinav Pratap Singh,Satyabrata Jit +6 more
TL;DR: In this paper, high quality fibrous Al-doped ZnO thin films with enhanced conductivity and optical response with controlled doping of Al are synthesized using low-cost sol-gel method.
Journal ArticleDOI
BiFeO 3 /CH 3 NH 3 PbI 3 Perovskite Heterojunction Based Near-Infrared Photodetector
Rishibrind Kumar Upadhyay,Abhinav Pratap Singh,Deepchandra Upadhyay,Ajay Kumar,Chandan Kumar,Satyabrata Jit +5 more
TL;DR: In this paper, a hybrid halide CH3NH3PbI3 and inorganic only perovskite BiFeO3 based heterojunction diode was proposed for near-infrared detection applications.
Journal ArticleDOI
Electronic band-offsets across Cu2O/BaZrO3 heterojunction and its stable photo-electro-chemical response: First-principles theoretical analysis and experimental optimization
Dipika Sharma,Rishibrind Kumar Upadhyay,Biswarup Satpati,Vibha R. Satsangi,Rohit Shrivastav,Umesh V. Waghmare,Sahab Dass +6 more
TL;DR: In this article, the authors used first-principles theoretical analysis of the electronic structure of the Cu 2 O/BaZrO 3 interface, and showed that valence and conduction bands are favourably aligned to absorb light and catalyse the Hydrogen Evolution Reaction.
Journal ArticleDOI
Fabrication and characterization of a ZnO quantum dots-based metal-semiconductor-metal sensor for hydrogen gas.
Smrity Ratan,Chandan Kumar,Amit Kumar,Deepak Kumar Jarwal,Ashwini Kumar Mishra,Rishibrind Kumar Upadhyay,Satyabrata Jit +6 more
TL;DR: A high selectivity of the proposed sensor with respect to ammonia, sulfur dioxide and organic vapours such as acetone, methanol, chlorobenzene, and chloroform has also been achieved due to nanostructure ZnO film.
